See the receipt prove itself.

Proof that an AI actually paid for what it got. One real receipt, three ways: watch it check itself in your browser, re-do the math yourself in a sandbox, then fire a real paid call to a live lane. No login, no key — your browser does the checking.

A real, already-anchored receipt — re-walked live

This pulls a genuine agent-call receipt from the public chain endpoint, then recomputes its hash in your browser. If our published leaf doesn't match what your own machine computes, the check fails. You recompute the leaf here; chain inclusion and the on-chain anchor are separate checks.

Build a receipt yourself

Pick a lane, send a request, and watch a result-bound receipt get assembled and hashed — live, in your browser.

Fire a real paid call

Start with Page Audit — the simplest real pay-then-prove job at $0.10 USDC. IronBridge never holds your key — your browser builds the payment, your wallet signs it, and you get a result-bound receipt back.

  1. Pick a live lane
    Page Audit (one USDC transfer), BNKR (one USDC transfer), or GitLawb (two USDC payments in one wallet confirmation to your wallet + a small fee).
  2. Your wallet pays on Base
    Page Audit and BNKR each use a single USDC transfer. GitLawb Pay sends both USDC payments in one wallet confirmation — not a single transfer. You sign it — we can't. Standard x402 v2 client compatibility is not yet claimed.
  3. The lane runs & returns the result
    Your payment and a fingerprint of the result are bound together when it settles.
  4. You get a keyless, re-walkable receipt
    Verify it yourself — exactly like step 1 — anytime, after we're gone.

Honest state: the pay rail is open. Unpaid calls get a pay request first. No verified outside sales yet; our own test payments stay labeled as tests.
